Background/Aim: Preoperative devascularization of intracranial meningioma by endovascular embolization has been performed in many institutes over the past 30 years. Advancement in microsurgical techniques and endovascular technology during the period may have offset or magnified the benefit of the procedure. The aim of the present study was to evaluate the effect of preoperative embolization on surgical resection of intracranial meningiomas. Methods: The results of preoperative embolization followed by surgical resection of intrancranial meningiomas at a local neurosurgical unit in Kwong Wah Hospital (KWH) were compared to the results of surgical resection of intracranial meningiomas without preoperative embolization at another local neurosurgical unit in Princess Margaret Hospital (PMH) between 1 January 2000 and 30 June 2003. Results: For convexity meningioma, there was no statistically significant difference in intraoperative blood loss, units of blood transfused or operation time between the embolized group and the non‐embolized group. For parasagittal and sphenoid wing meningioma, although the mean tumour volume was larger in the embolized group, there was less intraoperative blood loss and units of blood transfused, and shorter operation time in the embolized group as compared with the non‐embolized group. Conclusion: There was no significant effect of preoperative embolization on surgical resection of convexity meningiomas. However, the procedure appeared to be a useful adjunct to surgical resection of parasagittal and sphenoid wing meningiomas.
